题目/Title: The Relationship between Optical, UV and X-ray Emission in Active Galactic Nuclei

主持人/Host: 王建民

摘要/Abstract: 

Active Galactic Nuclei (AGNs) are powerful sources that emit across the entire electromagnetic spectrum. Understanding the relationship between their optical, UV and X-ray emissions is key to probing accretion physics and uncovering the complex processes that drive AGN activity. In this talk, I will briefly review the correlations between optical, UV and X-ray luminosity and variability in AGNs. I will explore how these multi-wavelength emissions are related on different time scales and how we can interpret these relationships within the context of AGN accretion flow. I will also discuss some observational results that remain difficult to explain, which may present significant challenges to classical black hole accretion theories. Additionally, I will highlight the multi-wavelength variability and correlation properties of some changing-look AGNs. Finally, I will discuss the prospects of AGN monitoring in the multi-wavelength time-domain era, emphasizing the potential for new insights into AGN accretion physics.
